Tomake one gallon of stain,=take one gallon of rain -water and add twoand one half ounces of extract of logwood and three and onehalf ouncesof gum catechu. The mixture is placed on a hot stove and heatedmoderate- I ly, being, at the same time, stirred two or three I times.When the mass is dissolved add one andone quarter dramof bichromate ofpotash.

\Vhen the bichromate of potash is dissolved add three drams ofconcentrated lye. Stir the mixture occasionally for about ten minutes.Then, after removing the foam or froth from the mass, add four drams ofpulverized resin gradually while the mixture is hot, and stir the wholemass for about ten minutes. .The mixture should be allowed to settle fora conple of days, when it will be ready for use.
